Why Choose Us
At Nemours duPont Pediatrics, Newark, we see patients for primary care medical needs like well-child checkups, sick-child care and immunizations, from birth until 18 years old. We offer extended hours that are more convenient for before- and after-school needs.
Your Child's Patient-Centered Medical Home
Our practice has been awarded Patient-Centered Medical Home™ (PCMH) Level 3 Recognition by the National Committee for Quality Assurance (NCQA). As part of our “medical home,” your child's primary care provider leads a care team dedicated to addressing your child’s comprehensive health care needs — arranging care with other qualified professionals as needed. The care team may include our doctors and nurses, care coordinators, psychologists, social workers and/or lactation consultants.
First Visit
A parent or legal guardian must accompany your child for the first visit. If a legal guardian rather than a parent accompanies your child, the guardian must bring guardianship and custody papers for your child to be seen.
